What Is The Graded Response Action Plan

  • GRAP is a set of emergency measures that kick in to prevent further deterioration of air quality once it reaches a certain threshold in the Delhi-NCR region.
  • Approved by the Supreme Court in 2016 and notified in 2017, the plan was formulated after several meetings that the Environment Pollution (Prevention and Control) Authority held with state government representatives and experts.

  • The result was a plan that institutionalised measures to be taken when air quality deteriorates.
  • GRAP is incremental in nature and thus, when the air quality dips from ‘poor’ to ‘very poor,’ measures listed under both sections have to be followed. Stage 1 of GRAP is activated when the AQI is in the ‘poor’ category (201 to 300), Stage 2 is when it’s in the ‘Very poor’ category (301-400), Stage 3 is when the AQI is the ‘Severe’ category (401-450) and finally Stage 4 is when it rises to the ‘Severe +’ category (more than 450).
